Android Studio javax.mail jar build error

Question

I'm trying to use the Gmail API to send emails. I've followed the Google documentation on how to do this. I need access to MimeMessage which is from the import:

javax.mail.internet.MimeMessage;

Since this is not included by default in Android Studio I downloaded the .jar files and did.

File -> New -> New Module -> Import .JAR

I also physically placed the javax.jar in the libs folder in Android Studio and referenced the jar from there.

my build.gradle(app) file looks like this in the dependencies section:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.google.android.gms:play-services:7.3.0'
    compile 'com.google.api-client:google-api-client:1.20.0'
    compile 'com.google.api-client:google-api-client-android:1.20.0'
    compile 'com.google.api-client:google-api-client-gson:1.20.0'
    compile 'com.google.apis:google-api-services-gmail:v1-rev29-1.20.0'
    compile project(':javax.mail')
}

However when I clean and build the project I get this error:

com.android.ide.common.ProcessException: org.gradle.Internal.ExecException.

I googled this and I'm pretty sure it has to do with my .jar file reference but I'm not sure how to fix this.

Add this to your dependencies section:

compile  'javax.mail:javax.mail-api:1.5.3'
